DOOR CONSTRUCTION FOR FLASH-LIGHT APFARATUS.

Application sied october 22, 1921." serial No. 509,674.

To @ZZ whom t may concern.'

Be it known that I, Ewan-inn L. JOHNSON, a citizen ofthe United States, and residing at Patchogue, inthe county of Suffolk and State of New York, have invented certain new and useful Improvements in'Door Constructions for F lash-Light Apparatus, of which the following is a specication, such as will enable those skilled in the arty to which it appertains to makeand use the same.

This invention relates to flashlight apparatus such as used by photographers in ytaking photographs, and the object of the invention is to provide yan improved door construction for apparatus-of this class which willfprevent the passage of thev dust or ash and smoke discharged-into a ash bag, from passinginto a room or compartment inwhich the. apparatus is used thusV permitting a photographer to take anumber of yphotoy graphs in rapid succession; afurther object ybeing to provide a door construction orapparatus of this class which will also facilitate the re-charging of the flash gun or device usually employed, which ash gun or device is mounted in connection with one,` of the members of my improved door construction; and( with these and-other objects in view the invention vconsists. in a door construction of the class and for the purpose lspecified whioh'is simple in construction and operation and eiiicient in use', and. which is constructed and operated as hereinafter described and claimed. r v

The invention is fully disclosed in' thefollowing speoiication, of which the accompanying drawing forms a part, in which the separate parts of my'improvement are designated by suitable reference characters in each of the views, and in which Fig. 1 is a backview of a flash-light apparatus of any kind or class sho-wing my improved door constructionmounted in connection therewith; v

f Fig. 4 a partial section on the line /1--4 of Fig. 1'; and,

Fig. 5a partial section ont theline 5-5 ofFig.3. f

Forthe purpose of illustratingone use-ot` my improved door construction, I have shown 1n the accompanying drawing a Hash bag 1() such as usually employed in apparatus of this class and which is mounted in conf nection with any kindv or class of framework 11 which supports thebag 10 in an operative position, and said framework, or the y tion shown in Fig. l5 of the drawing. The door member 17 is mounted upon hinges 20 and is provided at Vits periphery witha 'rabbet groove 21 to form a snug lit of said door member in vthe door opening14 as lshown in` Fig. e of the drawing, and said door member is providedwith'a projecting hookshaped" finger piece 22 which lis adaptedto engage the door member 16 to move the same from the position shown in Fig. 5 to the position shown in Fig. 4 in the operation of closing the door member 17 by hand, and a suitable catch device 23 is adapted to ycooperate with the door member 17 to hold it inaits closedr position as shown in Figs. 1 an 4.. i i

Mounted upon the linner face of the door i member 17 is a flash gun or device 24 of any kind or class, such as commonly employed in apparatus of the class under consideration, and a flexible tubing 25 is passed inwardly through the door member 17 andis connected with the flash gun or device 24 and by means of which the operative mechanisms of such gun `or device may be actuated externally of the apparatus.

The central `portion 13 of the frame also provided with a socket 26 by means oi which a tripod or other support 27 maybe connected therewith, or by means of which the apparatus may be mounted in connection with said tripod.

In the use of m improvement, the usual iash powder is p aceol in' the flash gun or device24 when the door, member 17 is in `ii is i lit? the position shown'in Figs. 3 and 5, after which said door` is closed or moved into the position shown in Figs. 1, 2 and a in which operation the hook-shaped finger 22 engages the door member 16 and moves it into the position shown in Fig. 4 against the tension of the spring hinge 18, and the door member 17 is held in its closed position by the keeper 23.

The flash powder may then be ignited in the usual manner and the door member 17 opened by releasing the catch 23, in which operation'the spring hinge 18 of the door member 16 will quickly operate to close said door member and force the door member 17 outwardly, after which a new charge of flash powder' may be mounted in the flash gun or device 24 and the above operation of opening the door member 17 and the closing ot' the door member 16 will not allow the es cape of any material amount or quantity of smoke, dust or ash ofthe ignited ash powder, and in this way the room or compartment in which photographs are taken will be kept free "from 'such smoke or powder, or the atmosphere of such room or compartment will remain-clear, thus permitting an operator or photographer to take an unlimited'number of pictures.

It will b'e understood that I am not necessarily limited to any particular form of frameworkfor supporting the flash bag 10 nor am I limited to the specific form of bag `herein `shown and described, and .Various other changes in and modifications of my improved door construction may be made, Within the scope of the appended claims, without departing from'the spirit of my invention or sacrificing its advantages.

Having fully described myv invention, what I claimas new and desire to secure by Letters Patent, is l 1. A door construction for flashlio'ht ap paratus comprising door members, earch pivotally secured to the flash bag and co-operating with eachother to close the door open ing to theflashbag in different positions of `said door members.

f2. vA door construction lfor flashlight ag- 'paratus comprising door members, each pivotally secured tothe flash bag and co-operat- Ying with each other to close the door opening tothe flash bag in different positions of rsaid door'members, one of said door members being adapted to be swung outwardly and a lla-sh ygun mounted in connection with said door member.

3.
